- Easy to deploy a container with the help of an ansible-playbook
- All these plays are using inbuilt ansible modules
- Docker installation and container spin up through the same playbook
----
## Pre-Requests
- Install Ansible on your Master Machine
- Basic Knowledge of ansible
##### Installation
[Ansible2](https://docs.ansible.com/ansible/2.3/index.html) (For your reference visit [How to install Ansible](https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html))

### Output Screenshot
----
## Reference
On this playbook was I used my old [nodjs](https://github.com/yousafkhamza/nodejs-dockerfile) container image so please be check the same. I have already explained how we create an image and container from the docker file.
----
## Conclusion
It's a simple Ansible playbook how we pulled an image from docker hub and then how to spin up a container from that image through ansible. I just uploaded the same for educational purposes and this playbook we used inbuilt modules so it is should more helpful for freshers who started ansible and docker.
